OK in that case you'll have the Windows 7 and Ubuntu Entry in your Windows Bootloader, when you start your PC.

To get the NVIDIA driver:For NVidia cards, the nvidia-experimental-310 NVidia driver is currently in the universe repository You can enable this repository by opening Ubuntu Software Center, selecting Edit | Software sources... and then enabling the Community-maintained free and open-source software (universe) option. In addition, for the latest vendor-supplied drivers enable the Proprietary drivers for devices (restricted) option on the Ubuntu Software tab.

This is to make sure you can get the latest Version for best performance and not just nvidia-current whichis 304.

I've actually been thinking of using Linux but never got to it, now when we get freebies from steam I've gotta test it, but yeah I understand nothing what's going on.

I am sure he is just Joking around.

First thing I would do is make sure you run all updates on the system. I seem to recall having a similar issue with another bit of software on 12.10 (when I shouldn't have, after a fresh install).

Then once that is done open the Unity Dash (hit the Ubuntu Logo at the top left) and search for Software Sources and open it. There will be an Additional drivers tab you should be able to use to install your drivers.
